Be a known that I, Cmms N. Menu.

. LAND, a citizen of the United States, and a resident of Dorranceton,in'the county of Luzerne and State of Pennsylvania, have inventedcertain new and useful Im rovements in Adding-Machines, of which t asfol lowing is a specification.-.

.My invention relates to adding machines and particularly to the wellknown Wales adding machine described and U. S. Patent #797032, grantedAugust 15, 1905, in which the printing mechanism: is

-mounted at the end of the device farthest from the operator andcomprises a laten on which the paper to receive the record'is supported,means for appropriately "sitioning the type atthe line of print in rentof the platen, means for prope toward the platen and an inking ribbon1nter osed between the type and t e platen.-

Ihe'ma'chine, in some of its styles, is likewise provided with meanswhereby the function of the accumulating mechanism may.

temporarily be interrupted without, at the same time, suspending thefunction of the remaining mechanism of the machine, so that an item maybe printed on the paper recording. strip on which the accumulated itemsare recorded without including it in the series of items accumulated oradding it into the total when these items are added. up.

In usin the machine in the manner last mentione it has been found byexperience that sometimes confusion ensues between the items printed onthe strips which. have been accumulated and those which have not. Inorder to avoid such confusion, or rather to lessen the tendency whichexists to have it occur, the machine is provided wlth means whereby theitems not to be totallzed'are re- I A corded in an ink of a differentcolor'from are recorded.

To that end I haveprovided the rib '15 I tion thereof; Fig} is a side elevation of the lsame, 'andtIfig. 5 1s a plan view of the finger pieceof thesupplementary key. V In the drawings, 1 is the frame of the machineonwhich arts are mounted. "These parts lnclu'de a ank of keys arrangedin denominational series, each key provided the ke depressed isinterposed in the paths of rac bars 20, one for each numeral wheel.

with. a stem by the de ression ofwhicha "stop corresponding to t enumeral value of These rack bars are each provided with I tooth racks'Qlon their upper edges and are supported at theirfront ends upon links 22suitably pivoted, either in the frame of the machine, or on someconvenient part thereof and at their rear ends upon the extremities ofbell crank levers 23- mounted to oscillate upon a shaft 24. The otherends of these levers 23 are pivotally connected with the printingmechanism. The rack .bars 20 are adapted to mesh with pinion-s 30 withwhich the numeral wheels are provided. These numeral wheels display inproper order on I.

their edges (not shown) the numbers from El. through 9 to 0, and are allmounted one common shaft 32, there being one numeral wheel for eachdenominational series of keys.

the rack barsare moved forward the extent It Wlll readily be understoodthat when of their movement is governed by the posi-- tion of the keystops'above referred to, and. this movement in turn governs the extent.of rotation of the numeral wheels when they are in mesh with the racks,during the return movementvof the latter to normal position. The forwardmovement of the racks to any extent is governed by other stops which areactuated by the key stops.

The machine is actuated by a handle 'wnich oscillates a shaft (notshown) which,

proper one is in a position opposite the oint of print. This point ofprint is in a 1 ed horizontal plane opposite a shaft on which the platen53 is mounted and which in turn is placed in a carriage 54 adapted tomove laterally across the rear end of the "chine. I -At each side of theframework of the machine there are provided bell crank levers 60 pivotedat 61. One arm 62 of the lever is hinged by a stem 03 to a key 6stprovided with a finger piece 65, which projects above the upper case ofthe machine. The other arm 66 of the same lever is provided at its lowerend with a foot or hook 07 adapted to swing in under the numeral shaft32 to support it. It is obvious that when this key 61 its stem 63 isdepressed the bell crank 60 will be swung to move the hooks (37 er theends of the shaft 32 so that when the rack bars 20 are oscillated thepinions cannot come into contact with them (see Fig. 1). In other words,the purpose of this key which is called an elimination key is tointerrupt the function of the adding mechanism so that while thedepression of the numeral keys will cause the registration of thecorresponding numbers on the strip of paper provided for that purpose,yet so long as this key is depressed, such items will not be added bythe machine.

At a convenient place on each side of the frame 1 are mounted verticalspindles 100, 101. On these are placed two ribbon spools 102 of usualconstruction, each provided with a central aperture 103 engaging withone of the spindles on which the spools turn and on which they are freeto reciprocate vertically. Each spool 102 is provided with an upperhorizontal flange 101 connected to its upper plate by a collar 105. Thespools are supported in a frame consisting of a cross piece 106 providedat each extremity with a fork 116 to embrace the collar 105. Projectingoutwardly from the cross piece 106 are ribbon guides 107 provided withhorizontal flanges, top and bottom, 108, between which an inking ribbon109 is adapted to move Back of the spool frame is a lifter comprisingtwo levers 120 rigidly fixed to a cross rod 121 suitably mounted in theframe of the machine, and which rod is adapted to cooperate with thelower end of the key stem (53, so that when the key (3-1 is depressedthe lever is tilted, which movement actuates the levers 120 and these.in turn lift the ribbon spools to bring the lowermost strip 119 to thepoint of print. This strip is of a different color from the upper partof the ribbon and is preferably saturated with red ink. It will thus beseen that when the elimination key is depressed and so long as it isheld depressed the item set up by the numeral keys will be printed inred ink and, of course, will not be added into the machine.

Secured to the cross rod 121 is a second rearwardly extending leverMounted. in a suitable aperture in the frame of the machine is asupplementary key 600 (pref erably arranged near to the key (5 1) andprovided with a depending stem ($01 adapted to engage with the end ofthe lever 222 to depress it and provided with a retracting spring 602surrounding the stem 601 within a casing 603 provided for that purpose,so that the key (300 will automatically be restored to its initialposition after depression.

A suitable spring 223 serves to ass st the restoration of the parts totheir original positions. A finger piece (301 is provided for the key600 and is preferably divided into colored panels on its upper surfaceas indicated in Fig. 5.

If the operator desires to have any item, which is set up on the numeralwheels thereby transferred to the printing mechanism, recorded in an inkof a different color from that normally employed, he will depress thesupplemental key 600. This in turn will actuate the lever and rest thelifter and the ribbon spools in the manner ii-evhi-usly described tobring the strip 119 to the point of print. So long as the key 000 iskept dcpressed the items thereafter recorded by the printing mechanismwill continue to litl printed in the distinguishing ink. on the ribbonstrip 119 until the key (300 is restored to its initial position. If, atthe same time, that the key 600 kept depressed the elimination key 64.is also depressed, nothing or:- c'urs and the position of the strip 119with reference to the point of print is not altered, because the lifterand the ribbon'spools have been already moved to place. In effect,therefore, while the actuation of the key 64 compels the printing of anitem recorded but not accumulated in a distinguishing color, theactuation of the key 600 enables the operator at his operation to recordany other item also in a distinguishing color.

What I claim as new is:-
